CONCRETE CONSTRUCTION.

Application filed January 23, 1919.

To all whom it may concern:

Be it known that 1, Ann GoMsnUn, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Concrete Constructions; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to concrete construction for buildings and the like and the primary object of the invention is to provide an improved concrete block or slab for use in constructing the walls, floors, ceilings, and the like of a building.

Another object of the invention is to provide an improved concrete slab or block for forming a unit of a building, which can be readily molded and transported to the desired place to form the units for the building being constructed.

A further object of the invention is to provide an improved concrete block or slab having transverse and vertically extending strengthening concrete ribs, which effectively braces the slab against all strains.

A still further object of the invention is to provide an improved means for connecting the slabs or units together at the corners of a building structure, so as to efiectively lock the blocks together.

A still further object of the invention is to provide an improved block or slab of the above character, which is durable and etiicient in use, one that is simple and easy to manufacture and one that can be placed upon the market at a reasonable cost.

WVith these and other objects in view the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings forming a part thereof in which Figure 1 is a perspective view of one of the concrete slabs or building units,

Fig. 2 is a horizontal section through the same,

Fig. 3 is a vertical section through a wall of a building showing the concrete slabs or building units in position,

Fig. 4- is a detail fragmentary horizontal section through a wall showing the method Specification of Letters Patent.

tion includes a plain outer side 4; having inwardly extending transversely disposed parallel spaced ribs 5 and parallel extending spaced vertical ribs 6. These ribs strengthen the outer sides of the sections and eifectively help the sections to resist all strains and to withstand a considerable amount of pressure or weight. he strengthening ribs 5 and G are tapered outwardly toward their free ends as at 7, so that the sections canbe readily removed from the forms or molds. Steel or iron reinforcing bars 8 are extended through the vertical ribs and similar reinforcing bars 9 extend through the transverse ribs 5 and form additional means for strengthening the sections. The outer sides of the transverse and vertical ribs 5 and 6 at the outer edges of the sections are formed with plain outer faces 10 so that the sections or blocks can be readily placed one upon the other. The sections 2 and 3 are placed together, so that the ribs 5 and 6 will abut each other and the sections will form a hollow block or unit of a building structure.

The blocks 1 can be molded of such length and height as to form an entire side of a room or the same can be formed of smaller size so that a number of the blocks when placed together will constitute a side or wall of a room.

In Fig. 3 is clearly illustrated the sections 2 and 3 placed together to form a block and one side of a wall of a building structure, and the block 1 is preferably placed upon a concrete base 11 which is embedded in the ground.

The roof erectors 12 are notched in the ordinary manner as at 13 and placed over the upper ends of the blocks 1.

In Fig. a is illustrated the manner of forming the end blocks and sections to form the corners of the building. The outer sections 2 of the blocks 1 have the corners beveled in opposite directions as at 14:, so that the sec tions can fit snugly together. The inner sections 3 have the inner corners thereof beveled as at 15 so as to form ahsnug joint. The outer vertical ribs 8 are extended beyond the vertical ribs 6 of the inner blocks 3, so as to form the outer corners of the building. Owing to the extended ribs 8 of the-outer sections 2 and the beveled corners 15 of the inner blocks 3, a hollow space 16 is formed at the cornersor meeting ends of the sections between the vertical ribs 8 and 6 of the sections 2 and 3. The transverse brace rods 9 have their terminals bent at right anglesas preferably troweled or otherwise finished so as to form a neat appearance which will be pleasing to theeye.

From the foregoing description, it can be seen that an improved concrete building block or slab has been constructed which is exceedingly strong and durable in construction, and which can be readily assembled to form a building or the like.

" In practice, I have found that the form of my invention, illustrated in the accompany,

ing drawings and referred to in the above description, as the preferred embodiment,

is the most eflicient and practical yet realiz- The outer faces of the sections 2 and 3 are ing the conditions concurrent with the adoption of my device will necessarily vary, 1 desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required without sacrificing any of the advantages of my invention as set forth.

7 What I claim as new is p In a concrete building construction, a pair of blocks formed from an inner molded sec tion and an outer molded section, each section having transverse strengthening ribs and vertical strengthening ribs, and metallic stay rods extending through said ribs, the outer vertical ribs of the outer sections of the blocks being extended beyond the outer vertical ribs of the inner sections of the block, the inner corners of the vertical rib of the outer section beveled to form meeting faces, the inner corners of the vertical ribs of the inner sections being beveled to form meeting faces, the inner and outer sections of the blocks at the ineetingpointsthereoi being arranged to form a hollow space, the staybars being extended into said hollow space, and a binding material adapted to be poured into the said space.

In testimony whereof I affix my signature in presence of two witnesses.
